I was looking at a brick wall through the EVF and the wall looked like I was looking through a screen and moving my head slightly. I switched to the LCD and it looked the same. I panned over to another flat wall (no brick pattern) and things looked normal? What caused this? The camera was still when I was looking at both walls.
